Heather Winterstein did not display typical signs of sepsis, a severe bacterial infection reaction, during her hospital visit in St. Catharines, Ontario, before her passing. Dr. Ron McMillan, an emergency medical expert from McMaster University, emphasized the challenge of diagnosing sepsis promptly despite its critical nature. Reviewing Winterstein’s records and autopsy report, he supported the clinical decisions made by Dr. Emad Nour, who treated her a day before her death.
Winterstein had complained of body pain, particularly in her right leg, but Nour did not find signs of infection upon examination. The ongoing coroner’s inquest, initiated in 2024 and conducted virtually, involves 22 witnesses over 13 days. Inquests aim to inform the public about deaths’ circumstances and may issue recommendations to prevent similar incidents.
McMillan highlighted the importance of infection in sepsis development, pointing out that Winterstein’s initial vital signs did not conclusively indicate sepsis. Nour’s decision not to conduct further tests or administer antibiotics was defended by McMillan to avoid unnecessary antibiotic use and potential resistance issues. The expert also explained the rationale behind Nour’s notation of “social issues” in Winterstein’s medical notes and how such factors can affect emergency department diagnoses.
